Light-uniforming anti-glaring structure and light-emitting device

摘要

A light-uniforming anti-glaring structure includes a light-polarizing reflection unit and a light-polarizing position adjusting unit. The light-polarizing reflection unit includes a multilayer reflector composed of a plurality of inter-stacked polymer films. One of the inter-stacked polymer films is a birefringence material layer that conforms to the condition of NX≠NY≠NZ, wherein NX is the index of refraction of light at X direction, NY is the index of refraction of light at Y direction, and NZ is the index of refraction of light at Z direction. The light-polarizing position adjusting unit is coupled with the light-polarizing reflection unit for adjusting the position of the light-polarizing reflection unit.

1. A light-uniforming anti-glaring structure, comprising:
a light-polarizing reflection unit including at least one multilayer reflector composed of a plurality of inter-stacked polymer films, wherein at least one layer of the inter-stacked polymer films is a birefringence material layer that conforms to the condition of NX≠NY≠NZ, wherein NX is the index of refraction of light at X direction, NY is the index of refraction of light at Y direction, and NZ is the index of refraction of light at Z direction; and a light-polarizing position adjusting unit coupled to the light-polarizing reflection unit for adjusting the position of the light-polarizing reflection unit; wherein the light-polarizing position adjusting unit includes a position adjusting ring surrounding the multilayer reflector for driving the multilayer reflector to rotate in 360 degrees, or for driving the multilayer reflector to flip-flop clock-wise or counter-clock-wise.
